Speaking after the midweek win, Mourinho revealed Matic had hurt his ankle sliding on the pitch to join the cup celebrations at Wembley.

But he confirmed the ex-Benfica star will be fit for the crucial Champions League clash against PSG at Stamford Bridge on Wednesday, the Blues drawing the away leg 1-1.

Matic was re-signed by the Chelsea for £21m in January 2014, having been allowed to leave for Benfica as a makeweight in the deal to sign defender David Luiz three years earlier.

A source close to the player said: “Matic is very happy to have returned to Chelsea in the first place and to have managed to make his mark in the club that had previously sold him, before he even got the chance to prove his worth.

“He is highly motivated and content at Chelsea. He will not think twice before putting pen to paper.”
